SPECIFICATION forming part of Letters Patent No. 602,123, dated April 12, 1898.

Application filed February 12, 1897. Serial No. 623,155. (No model.)

To all whom it may concern:

Be it known that we, FRANCES L. BRANDON and AMOS ROOP, citizens of the United States, residing at Hicksville, in the county of De-. fiance and State of Ohio, have invented a new and useful Bicycle Rim-Joint, of which the following is a specification.

This invention relates to the construction of wooden rims for vehicle-wheels, for bicycles, velocipedes, and other road-machines, and aims to secure a joint of maximum strength between the opposing or meeting ends of contiguous sections.

In the manufacture of this class of rims the sections are generally secured together by means of a glue or similar joint, the glue or like substance cementing the matching parts and preventing their separation. A vital feature of this invention is to secure a great extent of surface to receive the glue or cementing material and to provide a joint which will prevent the inroad of moisture, which tends to dissolve the glue and results in a loosening of the joint and a separation of the sections.

A further purpose of the invention is to secure a joint which will resist strain from any and all directions and hold the matching or contiguous parts in alinement and be capable of withstanding a shock or blow which would not destroy the rim at a part between the joints.

Other objects and advantages are contem-- plated and will appear in the course of the subjoined description; and to this and such other ends as pertain to the nature of the invention the improvement consists of the novel features which hereinafter will be more particularly set forth, illustrated, and finally claimed.

The improvement is susceptible of the various changes in the form, proportion, and the minor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which j Figure 1 is a plan View of a rim joint constructed in accordance with this invention. Figs. 2 and 3 are end views of matching sections. Fig. 4. is a central longitudinal sec- .tion of the joint illustrated in Fig. 1. Figs.

5 and 6 are perspective views of the matching ends of contiguous sections forming a rim-joint.

Corresponding and like parts are referred to in the following description and indicated in the several views of the drawings by the same reference characters.

The numerals 1 and 2 designate adjacent sections in the construction of avehicle-rim. The end of the section lis formed with a tapering pin 3, and the end of the section 2 is provided with a socket 4 of corresponding taper to snugly receive the tapering pin 3. Exterior to the tapering pin 3 are formed segments 5, concentric with the pin3 and tapering longitudinally from their inner to their outer extremities, whereby but'very little of the Wood is removed at the inner ends or base portions of the said segments. The tapering pin 3 in effect is. a tenon and the parts 5 are segmental tenons, and all the tenons are of similar and corresponding taper longitudinally, so as to require the removal of as little as possible of the Wood from the rimsection at the inner ends of the said tenons.

The matching end of the section 2 has segmental grooves 6, corresponding in position and form with the segmental tenons 5, so as to receive them and provide a close joint. The parts 7, intermediate of the segmental grooves 6, constitute segmental tenons which correspond with the segmental grooves 8 formed between the segmental tenons 5 of "the section 1. The segmental grooves 6 are of an inverse taper to the segmental tenons 7 and grow smaller toward their inner ends, thereby obviating the removal of too much of the wood in the formation of the joint and preventing the weakening thereof.

The tapering pin 3 and socket 4 provide means for holding the sections from displacement in any direction and enable the joint to be easily formed, as they provide centering means for the cutters when presenting the blanks or sections thereto to form the corresponding tenons and grooves.

A joint formed substantially as herein set forth provides a surface of great extent for the reception of the cementing or binding material and enables the matching sections to be forced together in such a manner as to secure a joint between the complementary parts which will practically exclude dampness and moisture from entering between the matching parts. By having the tenons of uniform taper throughout their length and with but very little of the material removed from between their inner or base portions the joint provided is as strong as any part of the rim and will resist strain from any point, thereby meeting all requirements of a joint of this character.

Having thus described the invention, what is claimed as new is- 1. In a joint for wooden rims, a section having a pin and tenons at the sides of the said pin, and a matching section having a socket to receive and wholly inclose the pin, and formed with grooves at the sides of the socket to receive the aforesaid tenons, substantially as and for the purpose described.

2. In a jointfor wooden rims, a section having a central pin, and a series of segmental tenons concentric with the pin and tapering longitudinally throughout their length, the outer ends being the smaller, and a matching section having a central socket, and a setenons of the first-mentioned section so as to snugly receive them, substantially as set forth for the purpose described.

3. In a joint for wooden vehicle-ri ms, a section having a centrally-disposed pin and a series of tenons at the sides of and concentric with the pin and extending from the inner to the outer edges of the rim, and a matching section having a socket to receive and wholly inclose the pin, and having a series of grooves at the sides of and concentric with the socket and extending through the inner and the outer edges of the rim and snugly receiving the tenons of the first-mentioned section, substantially as specified.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
